A841 grade A class 1 plates API Std 650 stainless and carbon steel tank

Combination of Design Loads
The inner tank API Std 650 stainless and carbon steel tank shall be designed for the most critical combinations of loading that result from internal pressure and liquid head, the static insulation pressure, the insulation pressure as the inner tank expands after an in-service period, and the purging or operating pressure of the space between the inner and outer tank shells, unless the pressure is equalized on both sides of the inner tank.

API 650 is the standard for welded tanks for oil storage. It specifies the API Std 650 stainless and carbon steel tank design, manufacturing, welding, inspection and installation requirements of oil tanks. API 650 is widely used in storage tanks with internal pressure less than or equal to 2.5 PSI.

In the year of 2015, customer from Peru oil refinery contact with us from Internet. After one month’s negotiation and quotation, they chose us as there supplier of raw steel plate API Std 650 stainless and carbon steel tank grade ASTM A36. We get an trail order of 300 tons in April. When the first ship arrived, they inspect the steel plate and very happy with the quality we supply. Then they put another 1700 tons order, we sent to them within 90 days. Our company management group visit the customer in the beginning of 2016 and the visit is very successful.

The main advantages of the external floating roof API Std 650 stainless and carbon steel tank are large storage capacity, suitable for storing more than 10000 cubic meters of crude oil. Compared with the internal floating roof API Std 650 stainless and carbon steel tank, the production of external floating roof API Std 650 stainless and carbon steel tank is simple and the steel consumption is less. However, the central drainage system of external floating roof API Std 650 stainless and carbon steel tank should be installed on the outer floating roof to ensure that the accumulated water can be discharged smoothly in rainy and snowy days, and avoid sinking accident.

As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales.
